Abstract
Abstract The gaseous fuel as it is delivered to the burner is heated to expand the same and compensate for expansion of the combustion air which occurs and alter the gas-air ratio. In an oven with a heat exchanger, in which air supplied to the oven burner and the oven exhaust are brought into heat transfer relation, the exhaust is directed over a heat section in the fuel line to the burner to effect the desired fuel temperature rise.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
152 words
In a gas burner system in which a combustible mixture of a gaseous fuel and air is burned for heating purposes, with the mixture relatively rich at ignition and the combustion air experiencing an apprEciable temperature rise following ignition and heating of the burner to operating condition, such that the mixture tends to become increasingly rich, means for compensating for the weight loss of the combustion air resulting from such temperature rise of the same to prevent such increase in the richness of the mixture, said means comprising a source of the gaseous fuel under pressure, fuel supply means extending from said source to the burner to convey the fuel to the latter for combustion, and means for heating the fuel to raise its temperature as it is conveyed by the fuel supply means to reduce the fuel weight proportional to said weight loss in the combustion air supplied to the burner.
Claim 2
Dependent Claim
152 words
In a gas burner system in which a combustible mixture of a gaseous fuel and air is burned for heating purposes, with the mixture relatively rich at ignition and the combustion air experiencing an apprEciable temperature rise following ignition and heating of the burner to operating condition, such that the mixture tends to become increasingly rich, means for compensating for the weight loss of the combustion air resulting from such temperature rise of the same to prevent such increase in the richness of the mixture, said means comprising a source of the gaseous fuel under pressure, fuel supply means extending from said source to the burner to convey the fuel to the latter for combustion, and means for heating the fuel to raise its temperature as it is conveyed by the fuel supply means to reduce the fuel weight proportional to said weight loss in the combustion air supplied to the burner.
Claim 3
Dependent Claim
26 words
A gas burner system as set forth in claim 1, wherein said heating means is powered by a portion of the heat produced by the burner.
Claim 4
Dependent Claim
138 words
In combination with a gas burner in which a combustible mixture of a gaseous fuel and air is combusted for heating purposes, with the mixture relatively rich at ignition, enclosure means for the burner which becomes heated thereby, a source of the gaseous fuel under pressure, fuel supply means including a delivery line for conveying the fuel from the source to the burner, means for supplying combustion air to the burner with the air experiencing an appreciable rise in temperature in such supply as a result of operation of the burner and the fuel-air ratio as a result tends to become increasingly rich, and means for applying heat to a portion of said delivery line to effect a compensating rise in the temperature of the fuel therein and prevent such relative increase in the richness of the mixture.
Claim 5
Dependent Claim
138 words
In combination with a gas burner in which a combustible mixture of a gaseous fuel and air is combusted for heating purposes, with the mixture relatively rich at ignition, enclosure means for the burner which becomes heated thereby, a source of the gaseous fuel under pressure, fuel supply means including a delivery line for conveying the fuel from the source to the burner, means for supplying combustion air to the burner with the air experiencing an appreciable rise in temperature in such supply as a result of operation of the burner and the fuel-air ratio as a result tends to become increasingly rich, and means for applying heat to a portion of said delivery line to effect a compensating rise in the temperature of the fuel therein and prevent such relative increase in the richness of the mixture.
Claim 6
Dependent Claim
23 words
The combination set forth in claim 3, wherein heat energy within said enclosure means is applied to the heating of said delivery line.
Claim 7
Dependent Claim
27 words
The combination set forth in claim 4, wherein said portion of the fuel delivery line is exposed within the enclosure means for the heating of the former.
Claim 8
Dependent Claim
27 words
The combination set forth in claim 3, wherein the means for supplying combustion air to the burner includes a blower for delivering the air thereto under pressure.
Claim 9
Dependent Claim
41 words
The combination set forth in claim 6, wherein the combustion air in the supply thereof to the burner is brought into heat exchange relation to heated products exhausted from the burner for cooling of such products and preheating of the air.
Claim 10
Dependent Claim
19 words
The combination set forth in claim 7, wherein the enclosure means for the burner forms an oven cooking cavity.
Claim 11
Dependent Claim
42 words
The combination set forth in claim 8, wherein said portion of the delivery line for the fuel is exposed to exhaust of the heated products from the oven cavity for the heating of the fuel in the supply thereof to the burner.
Claim 12
Dependent Claim
40 words
The combination set forth in claim 7, wherein said portion of the fuel delivery line is exposed to the heated products exhausted from the burner prior to the bringing the latter into the heat exchange relation to the combustion air.
Claim 13
Independent Claim
149 words
The method of regulating operation of a burner in which a mixture of a gaseous fuel and air is combusted for heating purposes, with the mixture relatively rich at ignition, and the combustion air in the supply of the same to the burner experiencing an appreciable temperature rise following ignition of the burner and heating of the same to operating condition, whereby the mixture tends to become increasingly rich, which comprises the steps of establishing a source of the gaseous fuel under pressure remote from the burner, heating the fuel in delivery of the same to the burner from said source to reduce the weight thereof in the combustible mixture, and relating such heating of the fuel to the aforesaid heating of the combustion air to compensate for the weight loss of the latter and prevent the noted increase in the richness of the mixture that would otherwise occur.
Claim 14
Independent Claim
149 words
The method of regulating operation of a burner in which a mixture of a gaseous fuel and air is combusted for heating purposes, with the mixture relatively rich at ignition, and the combustion air in the supply of the same to the burner experiencing an appreciable temperature rise following ignition of the burner and heating of the same to operating condition, whereby the mixture tends to become increasingly rich, which comprises the steps of establishing a source of the gaseous fuel under pressure remote from the burner, heating the fuel in delivery of the same to the burner from said source to reduce the weight thereof in the combustible mixture, and relating such heating of the fuel to the aforesaid heating of the combustion air to compensate for the weight loss of the latter and prevent the noted increase in the richness of the mixture that would otherwise occur.
Claim 15
Dependent Claim
34 words
The method set forth in claim 11, wherein a portion of the heat generated by the burner is applied to the heating of the fuel in the delivery of the same to the burner.
